Looks pretty solid.
I'd change the fact that you have Aoki above Melendez since Melendez dominated Aoki for 15 min.
I would also keep BJ in the top 5 and nudge Alverez out. (BJ 4 Maynard 5)
Not sure Wanderlei as much as I love him should be top 5 MW, his only victory was against Bisping who's biggest win was an extremely inconsistent Kang.
Then again at the same time I'm not sure who I would put in his place, so I digress.
